Answer:
a) Because when we exercise, we hydrolyze more ATP to ADP and Pi, and O2 is necessary for the hydrolysis, so we increase our intake of oxygen.
c) Because when we exercise, we produce more CO2 and increased ventilation is necessary to rid ourselves of CO2.
d) Because when we exercise, we use more ATP, and additional O2 is necessary to generate sufficient ATP.
Explanation:
During exercise , our body needs more energy in the form of ATP. This ATP comes from break down of food materials in the mitochondria of the cell during cellular respiration. With the addition of oxygen, more ATP is produced during respiration and this ATP is used by the body. With ATP, carbon dioxide is produced as a waste material which can be removed by exhaled out during breathing.

What’s question 1? (It says the info from it is needed)
Answer:
1/4 WR; 1/4 wr; 1/4 wR; 1/4 Wr
Explanation:
The principle of independent assortment indicates how different genes independently separate from one another when gametic (reproductive) cells develop. When a cell divides by meiosis, homologous chromosomes are randomly distributed to daughter cells, thereby different chromosomes segregate independently of each other. In consequence, each gamete has a unique combination of chromosomes. In this case, the two genes are on different homologous chromosomes, thereby gene variants (alleles) will be randomly distributed to daughter cells during meiosis (anaphase I) and thus the expected proportion of gamete genotypes will be 1/4 WR, 1/4 wr, 1/4 wR, 1/4 Wr.
Answer: D. her egg cells
Explanation: Mutations can only be passed down if the mutation happens in reproductive cells. Egg cells are reproductive cells. (Along with sperm in males.)
